Description

Created attachment 118481 NULL check added to prevent crash

In libX11/modules/im/ximcp/imDefLkup.c, Line #91 (closed), _XimICOfXICID returns NULL, Assigning: ic = null return value from _XimICOfXICID Dereferencing a pointer that might be null ic when calling _XimProcICSetEventMask

Hence, adding a NULL check to avoid crash.
